Not tested in situation. This being: - The presentation on Amazon does not pays tribute to the quality of this product, which is above the impression given here - Robust material, perfect machining steel: no stop projecting, thick plates (3 mm for the jacket structure), "full" steel arm, slightly shiny black paint. - Order received in two steps: a box with the stabilizer, another the next day with vest and arm. Ordered on February 3 received 10 and 11, from China. Double happened anonymous impeccable cardboard packaging. - The vest is easily adjustable with Velcro many large and strongly seize. I'm 1m80 for 92 kilos and I slipped with maximum clamping on a Tshirt: smaller jigs, provide thicknesses ... The shoulders are well padded, it is never in contact with the metal. Single gene, attachment to the sternum slightly based on the rib cage, a small DIY gaffer / foam and there will appear more. The ventral and dorsal padding is removable (zip) seen to change and wash the vest (which "descratche" of the metal frame). Well yes, we sweat when steady. Height adjustment is of great amplitude (approx. 20 cm), which allows to adapt to all torsos. I think for those who have a pronounced chest, the metal structure will be soon a gene, except to settle loosely and install shims on the shoulders, to be tested. Plastic clips are very firm: watch your fingers! I was able without difficulty to remove and don the vest by unclipping only 2 straps (on 6): Cinch right side and right; we can therefore désarnacher quickly. - The arm is attached and removed effortlessly vest is adjusted: there is no play Ditto at the other end with the shoulder stabilizer.. The spring arm is strong, a bit too much for my taste (tested with Sony NX30 full); I will say it is adjustable from hard to very hard with sturdy screws, not greased screws. The joints are very fluid, smoothly = arm or game is free including the stabilizer and camera. There are stops on both sides of joints that cash well. The spring pat on 4 lugs slightly rubberized: I will improve this ;-): with silicone stopper drawers - The stabilizer is in the same finish. The rubber material of the handle seems to last, it is sweet and firm; it is adjustable in height. The quick release plate has very fine settings and it is actually fast; comes with 2 screws (1/4 and 3/8 removable). The cons are very dense weight. There is a stop on the extension, which avoids ending up with against weight on the feet, appreciated! All clamps are firm and very hard. It comes with a bag in which I could also squeeze the arm but not the vest. - A CD of English explanation is provided: very brief and not very accurate. - As always with a steady, remains the most difficult: to balance!
